Abstract Background Controversy persists regarding the superiority of partial nephrectomy (PN) versus radical (RN) in pT2a renal cell carcinoma (RCC) tumors. In this study we aimed to compare survival and clinical outcomes between these two techniques Iran. Methods retrospective cohort, 96 patients who underwent either RN or PN for their RCC tumors were included. Overall (OS), cancer specific (...
PURPOSE Patients with ESRD secondary to acquired renal cystic disease have been reported to have a higher incidence of RCC than the general population. We examined the clinical and pathological significance of incidental renal masses in patients with ESRD. MATERIALS AND METHODS From January 1994 to July 2000, 852 consecutive patients with ESRD who were being considered for renal transplantati...
BACKGROUND Transcription factor E2F1 exerts effects on many types of cancers. As an upstream regulator of a host of genes, E2F1 can trigger diverse aberrant transcription processes that may dominate malignancy. Clear cell renal cell carcinoma (ccRCC) is the most common subtype in renal cell carcinoma which displays high malignancy and has a shortage of biomarkers in clinics. Our study aimed to ...
OBJECTIVES Recurrence rates for patients with locally advanced renal cell carcinoma (LARCC) remain high. To date the predictors of recurrence in those patients remain controversial. The aim of the present study was to assess the relapse pattern in those patients and identify predictors for recurrence. PATIENTS AND METHODS We evaluated retrospectively 112 consecutive patients who underwent sur...
PURPOSE To assess the relationship between De Ritis (aspartate aminotransaminase [AST]/Alanine aminotransaminase [ALT]) ratio and pathological variables and whether it is an independent prognostic factor. MATERIALS AND METHODS We analyzed 298 consecutive patients who underwent radical or partial nephrectomy for non-metastatic renal cell carcinoma (RCC) between 2006 and 2015. The association b...
UNLABELLED Renal cell carcinoma (RCC) clusters in some families. Familial RCC arises from mutations in several genes, including the von Hippel-Lindau (VHL) tumor suppressor, which is also mutated in sporadic RCC. However, a significant percentage of familial RCC remains unexplained. Recently, we discovered that the BRCA1-associated protein-1 (BAP1) gene is mutated in sporadic RCC. The BAP1 gene...
PURPOSE To assess and report the outcomes of laparoscopic partial nephrectomy )LPN) for T2 renal masses. MATERIALS AND METHODS Retrospective review of patients undergoing LPN for clinically localized renal masses ≥7cm between the years 2005-2016. Descriptive analyses were generated for demographics, lesion characteristics, perioperative variables (operative time, warm ischemia time (WIT), est...
High-mobility group AT-hook 2 (HMGA2) is involved in a wide spectrum of biological processes and is upregulated in several tumors, but its role in renal carcinoma remains unclear. The aim of this study was to examine the expression of HMGA2 and its relationship to the overall survival (OS) of patients with non-metastatic clear cell renal cell carcinoma (ccRCC) following surgery. The expression ...
Tubulocystic carcinoma of the kidney (TCK) is a recently established entity in renal neoplastic pathology. This review aims to give an overview of the clinical and pathobiological aspects of TCK. Grossly, the TCKs are well-demarcated multicystic lesions giving a "wrapped bubble" or "spongy" appearance. Microscopically, the tumors are composed of multiple, variably sized cysts separated by thin ...
We have recently reported tumor suppressive role of DAB2IP in RCC development. In this study, We identified one CpG methylation biomarker (DAB2IP CpG1) located UTSS of DAB2IP that was associated with poor overall survival in a cohort of 318 ccRCC patients from the Cancer Genome Atlas (TCGA). We further validated the prognostic accuracy of DAB2IP CpG methylation by pyrosequencing quantitative me...
